BALL-COCK.

SPECIFICATION forming part of Letters Patent No. 670,818, dated March26, 1901.

Application filed October 10, 1900. Serial No. 82,645. \No model.)

To all whom 711% may concern.-

Beit known that 1. JAMES M.SMITH,a citizen of the United States ofAmerica, residing at Olneyville, in the city of Providence, State ofRhode Island,have invented certain newand useful Improvements inBall-(Jocks, of which the following is a specification.

Figure 1 represents a side elevation of my improved ball cock as appliedto a watertank, which is shown in longitudinal section. Fig. 2 is anenlarged central vertical section of the ball-cock. Fig. 3 is a top planView of Fig. 2. Fig. 4 is a top plan view of the ballcock with the capremoved. Fig. 5 is an edge view of the cap.

Similar letters refer to similar parts in the different figures of thedrawings.

My improved ball-cock is designed to stand in a vertical position withina tank which holds the supply of water, saidtank being provided with asuitable discharge-pipe p and lifting-valve p.

The invention consists in the combination of a tubular-shaped standardhaving an enlarged middle portion inclosing a circular chamber orwater-passage which is divided by a partition from the inlet orwater-passage, said partition provided with a circular opening having anannular flange forming a valve-seat, said valve-seat having its axis inalinement with the axis of said standard, a discharge-pipe secured tothe said enlarged portion of the standard and communicating with thechamber or water-passage thereof, a valve-plug mounted in the standard,and a cam mounted in the standard and adapted to bear against the saidplug in closing the valve upon its seat, with means for holding said camin place within the standard and providing a ready adjustment for thereplacing of a valve-disk, as hereinafter described and claimed.

A represents a standard of a tubular form, having an enlarged middleportion b inclos' ing a circular chamber or water-passage c. A partitiond divides said chamber from the inlet or water-passage e, and saidpartition is provided with a central circular opening f, having anannular valve-seat f, against which the circular valve-disk g rests inclosing the said opening.

(t represents the discharge-pipe, having an exterior screw-thread toengage in the screwthreaded opening made in the side of the enlargedportion 1) of the standard.

The valve-disk g is made secure upon the end of the cylindrical-shapedplug 13, which fits loosely within the upper portion of the standard bya screw h.

C is a cam which is situated at the upper end of the standard and isdesigned to bear against the plug B in closing the valve-disk upon itsseat, said cam having trunnions M movable in vertical slots j j, formedin the circular wall of the standard, one of said trunnions having a hubintegral therewith and provided with an interior screwthreadedaperture,the axial center of which is at a right angle to the axialcenter of the cam-trunnions.

D is the ball or float of the usual construction, having a rodconnection Z, provided with an exterior screw-thread at one end toengage with the screw-threaded aperture in the hubJc.

E is a cap which is mounted upon the end of the standard to hold the camwithin the same,said cap having an ear m, provided with a circularopening centrally located, with a screw-threaded opening made in the earn, integral with the standard. This cap is secured to the ear of thestandard by the thumbscrew 0. Integral with the cap and diagonallyopposite the thumb-screw 0 a spurp turns downwardly and beneath aprojecting horn q, integral with the standard. This construction of acap not only holds the cam within the standard, but also facilitates theready removal of the plug B to replace a new valve-disk. The thumb-screwas it is turned loose a trifle allows the cap to be swung around to thedotted position, as indicated in Fig. 3, after which the cam and itsfloat connection are lifted out, and by means of a rod having ahook-shaped end to catch in the opening 1" the plug is readily removed.

The standard A has an exterior annular flange s, forming a base-plate,which rests upon a packing-ring t, surrounding the body of the standard.The lower portion of the standard projects through from the bottom ofthe tank T and is provided with an exterior screw-thread to engage thescrew-threaded end of the supply-pipe o, as shown in dotted lines inFig. 1. A check-nut w, interposed between the supply-pipe and the tank,compresses the packing-ring t and secures the standard firmly inposition.

The operation of myinvention is as follows: Assuming the parts to be inposition as illustrated in Fig. 1 and the Water at its highest level inthe tank, when the valve 29" is lifted by the pull-chain the Water as itdischarges through the pipe p will carry downward the float and by itsconnection with the cam G will swing the same to the position shown indotted lines. Simultaneously with this movement the pressure of Water inthe supplypipe '0 will raise the valve 9 from its seat and the WaterWill pass from the chamber a and through the small discharge pipe a tothe tank. When the valve 10" is closed, the water Will continue to flowthrough the discharge a until it reaches its normal level in the tank,when the cam C will have forced the valve 9 upon its seat and shut offthe sup: ply.

What I claim as new, and desire to secure by Letters Patent, is-

In a ball-cock, the combination of the t1i-' bular-shaped standard Aprovided with water-passages c and e, respectively, a dischargepipesecured to the standard and communicating with the aforesaidWater-passage c, said water-passages divided by a partition 01 providedwith a circular opening having an annular valve-seat, the plug B looselyfitting in the standard and having a valve-disk secured at one endthereof, the cap E mounted upon the standard and secured by thethumb-screw 0, said cap having a downwardly-bent spur p to catch beneatha projecting horn q integral with the standard, the cam O mounted in thestandard and interposed between said cap and said plug, said cam adaptedto operate through its connection with the float in closing the valveupon its seat, as shown and described.

Signed by me at Providence, Rhode Island, this 9th day of October, 1900.
